Oena Project, Republic of South Africa

Tango – African Star Minerals (“ASM”)

During the course of the year, Tango through its local subsidiary, ASM, acquired an additional pan plant (the “Plant”) with a 120 tonne per hour (“tph”) capacity to be used to support its stand-alone mining operation and the processing of pan tailings and bantam material (“Tailings”) left on site from previous mining operations. As previously reported (see news release dated 13 September 2018) during the 1st Quarter, ASM purchased a screening unit, 50t Terex dump truck and a Volvo 966 front end loader, which have now been delivered to site. Start of production is scheduled for mid-January 2019 following the end of the holiday break.

Moquita Project, Republic of Angola

Tango has a Services Agreement for Mining and Marketing of Diamonds with Cooperativa Mineira Do Moquita, SCRL (“Moquita”) on a 147 km2 portion of a concession located 50 km north of Lucapa within the Lauchimo River basin, Province of Lunda Norte, Republic of Angola. During the course of the 1st Quarter, the Angolan government launched operation “Transparency” which aimed to reduce diamond smuggling and reform the diamond sector. Endiama, the national diamond company of Angola, requested that all Cooperativas halt operations whilst Transparency is in progress.

Tango, with its strategic funding partnership with CC Mining Limited (“CCML”), a member of Consolidated Contractors Company Group, used this opportunity to finalize a detailed mine plan and complete a thorough assessment of the camp site and its upgrade requirements. Simultaneously, additional plant parts were acquired including a 50t scrubber, grease table and a 150 kva generator. The rental of earth moving equipment, including a front-end loader, dump trucks and an excavator was negotiated with a vendor and finalized.

Endiama is expected to allow the restart of operations of a number of Cooperativas, including Moquita, by end of December 2018, at which time Tango will begin mobilization and commissioning of the Moquita Mine.
